Nautili are free swimming animals that possess a head with two simple lens-free eyes and arms (or tentacles). They have a smooth shell over a large body chamber, which is divided into subchambers filled with an inert gas (similar to the composition of atmospheric air, but with more nitrogen and less oxygen ) making the animal neutrally buoyant ...

The current classification of the Nautilida, in prevalent use, [1] is that of Bernhard Kummel (Kummel 1964) in the Treatise which divides the Nautilida into five superfamilies, the Aipocerataceae, Clydonautilaceae, Tainocerataceae, and Trigonocerataceae, mostly of the Paleozoic, and the later Nautilaceae.

Nautilus is described by Verne as "a masterpiece containing masterpieces". [1] It is designed and commanded by Captain Nemo.Electricity provided by sodium/mercury batteries (with the sodium provided by extraction from seawater) is the craft's primary power source for propulsion and other services.
The Nautilitoidea is a superorder within the subclass Nautiloidea, comprising the phylogenetically related Nautilida, Oncocerida, and Tarphycerida.. The superorder has its roots in the Bassleroceratidae, the ancestral family of the Tarphycerida, sometimes included in the Ellesmerocerida.
This list of nautiloids is a comprehensive listing of all genera that have ever been included in the subclass Nautiloidea, excluding purely vernacular terms.The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (nomina dubia), or were not formally published (nomina nuda), as well as junior synonyms of more established names, and genera that ...
